摘要
将多操纵面布局飞机的约束控制分配问题表示为线性规划形式,采用原-对偶路径跟踪内点法进行优化求解,并给出了该算法的具体实现步骤。选用l1范数混合优化目标作为控制分配问题的优化目标。首先将控制分配问题转化为线性规划形式,然后采用原-对偶路径跟踪内点法进行线性规划问题求解。选用Admire飞机模型进行仿真实验,验证了该算法的有效性,并与直接分配法做了比较。仿真结果表明,该算法解决控制分配问题时,在运算效率、命令跟踪精度及分配效果方面均优于直接分配法。
Control allocation problems of aircraft with multi-effector are formulated in the form of linear programming,primal-dual path following interior-point algorithm is utilized to solve the optimal solutions for control allocation problems,and the implementation of the algorithm is given in detail.The mixed l1 norm optimization objective is used for control allocation.The control allocation problem is first transformed into linear programming formulation,then the primal-dual path following interior-point algorithm is served for the solution.The effectiveness of the algorithm is validated by the simulation on the Admire aircraft model,and comparisons are made with direct control allocation method.Simulation results show that the interior-point algorithm outperforms the direct control allocation method in terms of computational efficiency,command tracking accuracy and control allocation effects.
